rick, thanks very much for joining us. talk about this relationship between president mandela and president obama. >> you know, wolf, i thought the president was very eloquent yesterday, talking about what president mandela meant to him. in many ways i think mandela was partly responsible for barack obama's own political awakening. one of the great legacies of mandela particularly in america is that it was an awakening for so many people that people were looking at south africa, this land that with terrible prejudice, terrible authoritarian government and we were looking at it as almost a proxy for what had happened in america during the civil rights movement and i think it awakened and it was a revelation for many, many americans. >> i'm sure president obama and i'm sure you'll agree was deeply disappointed when he was in south africa earlier this year, with his family, he was not able to go and meet president mandela, because he was so gravely ill. i'm sure he would have loved to have done that, but he obviously couldn't
